So Datasnap in Delphi 2007 does anybody knows if it works with Windows 7?

After reading Marco Cantu I included Midalib on Uses both Client & Server but I am still getting "Error Reading ADOConnection. Operation is not allowed in this context " on Server Side & "Catastrophic Failure" on Client Side.

Delphi 2007 DCOM datasnap works with Windows 7 and Windows 2008(R2). But what Windows version are you using? Home or Pro/Enterprise/Ultimate? The Home version has several network features "neutered".

If you try to run DCOM datasnap without knowing how DCOM works and how to configure it, you're heading into a lot of trobles. You have to run dcomcnfg.exe and configure your server (and some dcom global settings). Also, when using COM based libraries like ADO you have to know how to setup the hosting application properly. DCOM is a powerful but complex beast.
